Which algebraic representation of a transformation on a coordinate grid does NOT preserve congruence? A. ( x, y) -> ( x + 6, y + 6)
B. (x, y) -> (-x, y)
C. (x, y) -> (6x, 6y)
D. (x, y) -> (-y, x)

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
